According to Animeondvd.com the show Tweeny Witches was picked up by Media Blasters.

Here is the announcement on the website:

Media Blasters Acquires Tweeny Witches (05:35 PM EDT): John Sirabella is the master of sneaking in some license news in a rather amusing way when people least expect it. In a discussion thread about titles we listed earlier today, he posted, "OH Yeah...almost forgot we just got the materials in for Tweeny Witches... I never mentioned it at the cons. Do not worry the titles announced will be coming and more on the horizon..maybe even some bigger ones to announce..who knows."

There is currently no news on whether this will be a sub and dub or just sub release. Also no news on whether Media Blasters has picked up the second season has been confirmed.
